Not 100% sure if these are actual errors, as the only historical versions of the list I could easily find went by the name 'SUMBUDDIERUVVER’S BLOOD AXE WAR HORDE ORK ARMY'. However, there's a number of inconsistencies in the BLOOD AXE KOMMANDANT UG SKRAGGA MORKRUMPS’S KORPS ORK ARMY list. Both are labeled as v1.3 with Neal Hunt as the army champion, so I'm assuming they're supposed to be the same.

Warband formation list entry: includes Killa Kanz as an upgrade option. The 'Sumbuddieruvver' version does not include Killa Kanz. Killa Kanz and Dreadnoughts do not appear anywhere else in the list, and do not seem to be in theme. Not sure they should be here or if they're a cut and paste error from other Ork lists.
Bommer's formation list entry: 'Ork Bommer'. Unit reference list: 'Bommer'. This is inconsistent naming.
Bommers Special Rule indicates that they can be part of a squadron of Fighta Squadron. The formation list does not support this; they are two separate entries. Either this special rule needs to go, or there should be an option in the Fighta Squadron to upgrade or add Bommers. In the 'Sumbuddieruvver' version of the list, they were only upgrades to the base Fighta Squadron.
Special Rule Deth From Above indicates that there are Drop Kanz, Kroozers and Battlekroozers. The unit reference list supports this. The main list entries (and points) are missing. 'Sumbuddieruvver' version of the list had the following three additional entries:
Kill Kroozer, One Kill Kroozer, May be upgraded to Ork Battlekroozer for +50 points, 200
Gargant, One Gargant, n/a, 650
Great Gargant, One Great Gargant, n/a, 850

Several formation entries reference a +50 point upgrade 'Warkopta'. This unit does not appear in the unit reference list. Based on the 3.04 Supplemental list here:
viewtopic.php?f=83&t=22042 it should have the following profile:
Ork Warkopter
Light Vehicle
35cm 5+ 6+ 6+
2x Big Shoota 30cm AP6+ / AT6+
Skimmer, Transport (2 from: Boyz, Kommandos or Nobz. Plus 1 Grot unit in addition to other units, May not carry Meganobz)
